Question

My example

<?php
if(something){
$message = "set";
}

echo $message; // but I can get error that variable is not unidentified ?>

My question how to check do variable is initialized to not get error “unidentified variable”

Answer 1

try something like

$message = NULL;
if(something){
$message = "set";
}

if($message){
   echo $message;
}

Codepad

or check that variable is set by isset

echo isset($var)?$var:'';
